83999-44-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83999-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,9 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83999-44:
(7*8)+(6*3)+(5*9)+(4*9)+(3*9)+(2*4)+(1*4)=194
194 % 10 = 4
So 83999-44-4 is a valid CAS Registry Number.

Organocatalytic enantioselective protonation of silyl enolates mediated by cinchona alkaloids and a latent source of HF

Poisson, Thomas,Dalla, Vincent,Marsais, Francis,Dupas, Georges,Oudeyer, Sylvain,Levacher, Vincent

, p. 7090 - 7093 (2008/09/17)

Hidden benefits: The enantioselective organocatalytic protonation of silyl enolates has been achieved by using readily available cinchona alkaloid catalysts (1) and a latent source of HF that delivers "at will" the active catalytic hydrogen fluoride salt

ENANTIOSELECTIVE DEPROTONATION OF TWO RACEMIC CYCLIC CARBONYL COMPOUNDS BY A CHIRAL LITHIUM AMIDE

Eleveld, M. B.,Hogeveen, H.

, p. 631 - 634 (2007/10/02)

The cyclic carbonyl compounds 2 and 8 have been obtained in optical active form (o.y. 46percent and 36percent, respectively) from the racemic compounds by a deprotonation/protonation sequence, using chiral lithium amide 1.The optical activity of 2 is caus

Oxidation of Enol Silyl Ethers: Preparation of Aeginetolide, Dihydroactinidiolide, and Actinidiolide

Rubottom, George M.,Juve, Henrik D.

, p. 422 - 425 (2007/10/02)

The preparation of the C11-terpenic lactones aeginetolide (1), dihydroactinidiolide (2), and actinidiolide (3) by using 1,3,3-trimethyl-2-(trimethylsiloxy)cyclohexene (9) as a common precursor is discussed.The key steps in the synthetic route involve the sequential m-chloroperbenzoic acid (MCPBA) oxidation and acetylation of 9 and of the siloxy diene 13 derived from 9.
